Abstract

trata-se de uma conexão tubular que compreende um eixo geométrico longitudinal, um membro de pino que compreende uma extremidade distal do pino, uma rosca afunilada do pino que tem um ângulo de funil constante do pino a1 com relação ao eixo geométrico longitudinal e, uma superfície de vedação do pino localizada entre a rosca do pino e a extremidade distal do pino e, um membro do tipo caixa que compreende uma extremidade distal da caixa, uma superfície de vedação da caixa e, uma rosca do tipo caixa afunilada que tem um ângulo de afunilamento constante do tipo caixa ß1 com relação ao eixo geométrico longitudinal e localizado entre a superfície de vedação da caixa e a extremidade distal da caixa e, em que a rosca do pino é configurada para cooperar por meio de combinação com a rosca do tipo caixa ao longo de uma área de cooperação, ao mesmo tempo que tem uma interferência radial da rosca entre a rosca do pino e a rosca do tipo caixa ao longo de pelo menos parte da área de cooperação, a superfície de vedação do pino e a superfície de vedação da caixa são configuradas para entrarem em contato entre si após a combinação de uma maneira vedante ao mesmo tempo que formam uma vedação do tipo metal a metal e, o ângulo de afunilamento do pino a1 é maior do que o ângulo de afunilamento da caixa ß1.It is a tubular connection comprising a longitudinal geometry axis, a pin member comprising a distal end of the pin, a tapered pin thread that has a constant funnel angle of the pin a1 with respect to the longitudinal geometry axis, and a pin sealing surface located between the pin thread and the distal end of the pin and a housing-like member comprising a distal end of the housing, a housing sealing surface, and a tapered-housing thread having an angle constant-tapering type ß1 with respect to the longitudinal geometrical axis and located between the housing sealing surface and the distal end of the housing and wherein the pin thread is configured to cooperate by combining with the housing-type thread along a co-operative area, while having radial thread interference between the pin thread and the box type thread over at least part In the cooperation area, the sealing surface of the pin and the sealing surface of the housing are configured to contact each other after combining a sealing manner while forming a metal to metal seal and the angle of taper pin a1 is greater than taper angle of case ß1.
